Answer from: dianactorres

Work = force x distance
22N x 16m = 352 J

Answer from: QuestionsAnsweredNow

Option (C) is the correct answer.

Explanation:

Work is defined as the energy required when force is applied in a certain direction.

The expression for work, force and distance is as follows.

W = F × d

where, W = work

F = force

d = distance

It is given that force applied to drag the box is 22 N and distance is 16 meters. Therefore, calculate work done as follows.

W = F × d

= 22 N × 16 meters

= 352 Nm (1 Newton meter = 1 joule)

or, W = 352 J

Thus, we can conclude that amount of work done is 352 J.

You need to be more specific. i really don't know what a "motion map" is.you can draw a graph of an object's position, distance, displacement, speed,velocity, or acceleration versus time, or you can draw a graph of the object's x-position versus its y-position and not give any information about time at all.if the graph presents position or displacement against time, then constant velocity is a straight line . . i.e. a line that has constant slope.if the graph shows speed against time, then constant velocityis a horizontal piece of line.if the graph shows acceleration against time, then constant velocity is a piece of line that lies on the x-axis . . it's value is zero.
